Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Marine Grade Construction: The MBTA8100 tube features a
8" waterproof woofer. The enclosure is certified
salt fog and UV resistant for 5 years and the included mounting hardware is
The 8" woofer is powered by a built-in 100-watt RMS amplifier.
Moisture Resistant Enclosure: The
enclosure is moisture, UV, and salt fog resistant for reliable operation in all
Low-pass Crossover: This unit
has a low-pass filter at 85Hz with a slope of 18dB/octave.
The subsonic filter, set at 35Hz, prevents really low frequencies from being
amplified. This allows the amplifier to run more efficiently with increased
Remote Level Control: Using

into a corner, and there should be 2 to 4 inches between the woofer and the
corner into which it is pointing.
Wire: the 16-gauge power lead is only 11.25"
long, so additional wire is usually required to extend it to the battery
Wire: required only when using the
Patch Cord: required only when using
the low-level inputs
